Click on address bar and press RETURN lose HTTPS protocol

Try this: [ul] [li]go to https://blog.rabin.io[/li] [li]click on address bar[/li] [li]press RETURN / ENTER on the keyboard[/li] [/ul] You can see that now the address loaded is http://blog.rabin.io/, so you switch from HTTPS to HTTP. Is this an expected behaviour or a bug? I am used to do this way if I want to refresh the page, when I previously submitted a form, in order to avoid the re-submitting of the form.
